Comparison of laparoscopic rectopexy with open technique in the treatment of complete rectal prolapse: clinical and...

The aim of this retrospective study was to compare the functional and clinical results of laparoscopic rectopexy with those of the open technique in two similar groups of patients with complete rectal prolapse and fecal incontinence. Between November 1992 and June 1997, 21 patients underwent abdominal rectopexy. Thirteen patients (group A: 12 women and 1 man, mean age 52.9 years, range 28-70) and 8 patients (group B: 8 women, mean age 58.2 years, range 20-76) were submitted to Well's rectopexy by the open technique and the laparoscopic approach, respectively, without division of the lateral rectal ligaments. Assignment to each group was done randomly. Before the operation, a detailed clinical history was taken, and patients were studied with inspection and digital examination of the anorectum, proctosigmoidoscopy, determination of pancolonic transit time, dynamic defecography, anorectal manometry, and anal electromyography. After the operation, all patients underwent perineal physiotherapy, external electric stimulation, and perineal biofeedback. The mean follow-up time was 29.5 months (range 6-54) in group A and 25.7 months (range 8-45) in group B. Values were compared by chi-square, Mann-Whitney U, and Wilcoxon tests, as appropriate; differences were considered significant at p < 0.05. In both groups, dyschezia and fecal incontinence improved significantly (p < 0.05) after the operation. Basal pressure of anal sphincter, squeezing pressure, and rectoanal reflex improved without significance, whereas anoperineal pain was not significantly reduced. In group B, the postoperative hospital stay was shorter than in group A, with a marked reduction of costs. Laparoscopic Well's rectopexy has the same clinical and functional results as the open technique, with a shorter postoperative hospital stay and lower costs.
